FAQs

What is DS1220AB-200+?

The DS1220AB-200+ is a 16k nonvolatile SRAM (NVSRAM) memory module designed by Maxim Integrated. It combines the features of a traditional static RAM with a nonvolatile element to retain data even when power is removed. This makes it suitable for applications requiring data persistence and fast read/write access, such as industrial automation, automotive systems, and data logging.

How Does DS1220AB-200+ Work?

The DS1220AB-200+ operates as a nonvolatile memory module, utilizing a combination of volatile and nonvolatile storage elements. When power is applied, data can be read from and written to the module at high speed like a traditional SRAM. When power is removed, the nonvolatile element preserves the data, ensuring that it can be retrieved upon power restoration. This dual functionality makes it suitable for applications that require both fast access and data retention.

How Many Pins does DS1220AB-200+ have and What are the Functions of the Pinout Configuration?

The DS1220AB-200+ is housed in a 24-pin DIP (Dual Inline Package) package. The pinout configuration includes:

Chip Enable (CE): Controls the operation of the memory module.
Output Enable (OE): Enables the outputs for reading data from the module.
Address Inputs (A0-A10): Select the memory location for read or write operations.
Data Inputs/Outputs (DQ0-DQ7): Bi-directional data lines for read and write operations.
Store Voltage (VSTORE): Supplies power to the nonvolatile element for data retention.
Power (VCC, VSS): Supply voltage and ground pins.

What are the Pros and Cons of DS1220AB-200+?

Pros:

Nonvolatile Storage: Retains data without the need for a backup power source.
Fast Access: Provides fast read and write access similar to traditional static RAM.
High Endurance: Supports a large number of read and write cycles, suitable for frequent data updates.
Wide Operating Voltage Range: Operates over a wide range of supply voltages.

Cons:

Complex Pinout: Requires careful attention to pin functions and timing considerations for proper operation.
Cost: Nonvolatile SRAM modules may have a higher cost compared to standard SRAM due to the added nonvolatile feature.
Finite Retention Time: The nonvolatile element has a limited retention time, requiring periodic refresh cycles.

Are There Any Equivalents/Alternatives to DS1220AB-200+ for Recommendation?

The DS1250Y from Maxim Integrated is a similar nonvolatile SRAM module with different capacity and package options.
Alternatives to the DS1220AB-200+ include the FM1608 from Cypress Semiconductor and the M48Z02 from STMicroelectronics.
